Answer:
50
Step-by-step explanation:
Wen: 30% of the total number of cards = 60 cards
Set this up as an equation
30/100 = 60/x
Cross multiply
30 × x = 100 × 60
30x = 6000
Divide both sides by 30 to isolate the variable
x = 200
There are 200 cards total
Gina: 25% of the total 200 cards
Set this up as an equation
25/100 = x/200
Cross multiply
25 × 200 = 100 × x
5000 = 100x
Divide both sides by 100 to isolate the variable
50 = x
Gina's share is 50 cards
